DSC SETUP Menu

The [DSC SETUP] menu configures the radiotelephone's DSC section.
MMSI: Displays ship's MMSI no.
SIG DETECT S-LEVEL: Adjust the carrier sense threshold for DSC and PSTN. DSC transmission
is delayed if the carrier level is higher than the level set here. Also, determine whether a DSC fre-
quency is in use or not. A DSC message is not transmitted when the signal strength of the DSC
frequency is higher than that set here. When the DSC frequency becomes clear, the DSC mes-
sage is sent.
The carrier is checked at a specified interval during PSTN communications, and if the carrier level
is lower than set here the line is disconnected.
